Medeco Lock

I have a double cylinder deadbolt lock on an exterior door that came with the house we bought three years. My question is can I change the double deadolt to a single deadbolt lock? I was able to remove and reinstall a single deadbolt lock while refinishing a different door recently, but I can't find any info on if it's even possible to do this.
Thanks in advance for any help you may be able to provide!

If it is a completely separate deadbolt, not a part of a "handleset", then it is an easy job to change the entire assembly. You MAY be able to buy just the inside turn button from a lock shop if you want to keep the rest of the assembly.

A lot of places that sell locks will rekey them for you, just bring your old key .... if keeping everything keyed the same is important to you.

Yes you can; both single and double cylinder deadbolts use the same door prep, as long as it's a typical cylindrical (tubular) stand-alone deadbolt. As Furd said, most Medeco inside cylinders can be swapped out for the thumbturn, the problem would be finding the thumbturn assembly only available for sale.

If you want to save $$ and don't mind using a key as the inside thumbturn, but the problem is anyone could remove the key, you can file a "barb" or back-angle on a part of the key so that when inserted, it can't be removed, unless the lock is disassembled. It's the poor man's T-turn.

I've learned based on someone else's house growing up that if you leave the key in the cylinder for a couple years as rstripe's 'poor man's T-turn' that the key is going to quit being removable anyway.

Quite true, especially in a corrosive climate. After living in a condo on the beach for several years, certain metals that remain in contact with one another can rust together.
